@OPC: Yep, it's indexed properly. Good job. I wouldn't know how to do that. The video was informative.
@44AMP: I want to be fair to the original poster. My gun safe is literally crammed, and so instead of adding more rifles, for the past two years I have been focusing on upgrading optics. It's amazing how much optical quality has improved over the past 40 years. Multi-coated lenses, better clarity at all magnifications, and a wider variable magnification range, seem to come with a penalty of a larger diameter and longer eyepiece. (Plus, I add Butler Creek flip covers, which also increase the diameter slightly.) Some of my new scopes have been a challenge to mount. I'm becoming a fan of rifles with a 60 degree bolt lift.
